VEHICLE-SUSPENDING DEVICE.

Specification of Letters Patent.

Patented Aug. 13, 1907.

Application filed May 17,1907. Serial No. 374.242.

To all whom it may concern:

Be it known that I, WYNFORD BRIERLEY, a subject of the King of England,residing at Parkstone, Boombe Road, New Malden, in the county of Surrey,England, journalist, have invented certain new and useful Improvementsin Vehicle-suspending Devices, and I do hereby declare the following tobe a full, clear, and exact description of the invention, such as willenable others skilled in the art to which it appertains to make and usethe same.

My invention relates to vehiclesuspending devices, including a compoundspiral or convolute spring, thereby balancing the vehicle more evenlyand greatly reducing vibration, said compound springs having a tendencyto always restore the parts to their normal position when displacedtherefrom.

In the accompanying drawings Figure 1 is a side elevation of a part of avehicle, showing my invention applied thereto, and Fig. 2 is an end viewof the same.

a indicates a compound convolute spring, with the coils arranged inreverse directions, whereby any displacement from the normal positionwill produce a tendency to restore the parts to said normal position. Ithas been found in practice that such a compound spring is far superiorto separate oppositely acting springs, one reason being that it is verydiflicult to get springs of the same tension.

it shows the wheel axle, and 1' indicates a double bracket formingsupports for the axle j. Through the upper ends of the bracket 71 passesa rod m. On the ends of this rod m are fitted the ends of two pairs ofcompound springs a, such as already described, one pair on each side ofbracket, the middle portion of these springs being attached to the axlej by means of the pin 6.

On the axle j is keyed one end of an arm n, to the other end of which ispivoted a lever o. The other end of this lever is attached to theframework of the vehicle.

10 shows a spring box which may be used when it is desired to useordinary springs in addition to the compound springs a.

Having thus described my invention, I claim:

1. In vehicle suspending devices, the combination of the vehicle axle,:1 cross shaft above the same, compound convolute spiral springsfastened at the center to said cross shaft. an arm extending up fromsaid cross shaft. and a support connected to the vehicle frame andpivotally connected to said arm, substantially as described.

2. In vehicle suspending devices, the combination of the vehicle axle, across shaft thereon, compound convolute spiral springs each havingitscentral portion attached to said cross shaft, an arm fastened to saidcross shaft, and a lever carried by the vehicle frame and pivot-allyconnected to said arm, substantially as described.

In testimony whereof, I aifix my signature, in presence 01 twowitnesses.

WYNFORD BRIERLEY.
